No Legal I.D.'s on Lubbock's 100.7 Fox Talk simulcast?

[Garrett]

How come 100.7 FM is not required to run a legal I.D.? I've been listening to this for a couple of months now, and never heard a Legal I.D.

I thought all FM's were required to run a legal I.D. Was I wrong about this? Can someone from the FCC or knowledge of such chime in on this?

Quoting from the applicable rule for FM translators:

"By arranging with the primary station whose signal is being rebroadcast to identify the translator by call sign and location. The identification must occur 3 times daily: once between 7 AM and 9 AM, once between 12:55 PM and 1:05 PM, and once between 4 PM and 6 PM. Stations which do not begin operating before 9 AM must provide the identification at the beginning of the broadcast day."

100.7 is a translator (K264AN) and they might be using FSK ID to legally ID the translator. FSK is inaudible over the air. You would need a decoder to hear it. Some low power transmitter manufactures (like PTEK) include FSK ID built into the transmitter to ID the translators.

Wow! You can do that?
Is that possible for regular full power too?

I believe translators can also ID in Morse code. Maybe they could work that into their news intro?

Yes. From 74.1283(c)(2):

(2) By transmitting the call sign in International Morse Code at
least once each hour. Transmitters of FM broadcast translator stations
of more than 1 watt transmitter output power must be equipped with an
automatic keying device that will transmit the call sign at least once
each hour, unless there is in effect a firm agreement with the
translator's primary station as provided in Sec. 74.1283(c)(1) of this
section. Transmission of the call sign can be accomplished by:
(i) Frequency shifting key; the carrier shift shall not be less than
5 kHz nor greater than 25 kHz.
(ii) Amplitude modulation of the FM carrier of at least 30 percent
modulation. The audio frequency tone use shall not be within 200 hertz
of the Emergency Broadcast System Attention signal alerting frequencies.

74.1283(c)(1) allows you to ID the translator by having the primary station run IDs for the translator. You only need to ID three times a day when you do it this way -- once between 7 and 9am, once within 5 minutes of 1pm, and once between 4 and 6pm. The translator may choose either method.

Is that possible for regular full power too?

No.

It's not officially full power but I'm surprised the threshold is 25 khz. That can go a long way in a flatland like Lubbock.

25 kilohertz, not 25 kilowatts. They can, in effect, hook up a Morse key* to shift the frequency between 100.7 and 100.725.

With the appropriate receiver (fairly rare) you probably could decode the Morse at a considerably greater distance than that at which you could receive the program audio.

* in fact, they'd use a microcontroller to generate the Morse. In the days when the rule was first enacted, they used a toothed wheel & a microswitch!

Any restrictions on words per minute that code is sent?

Talk about Deja Vu. I recall a reel-to-reel automation system that had that toothed wheel to keep the hour's music sequence on time.

KJTV is now running a shared-ID for the simulcast in the morning.

i don't pick 100.7 up very well daytime but, have you noticed, Crystal Clear signalon 100.7 at night? are they boosting power to cover for 950's nightime coverage... just wondering.
